Limit guest user (actually all users) to use coupon only once

[apiuser]

Feature request from seansan, posted on GitHub Mar 29, 2016

Request: build in simple functionality to inlcude guest users (hence their email) in the check if a coupon code is already used. @sonalagr

Steps to reproduce

1. Suppose we set-up a coupon code that can only be used once
2. Guest users can check out with 2 orders and the coupon is still valid

Expected result

1. Second order the coupon code is invalidated (client already ordered with that username OR e-mail
2. ...

Actual result

1. User can use the coupon code again

Possible solution

• can be a setting in the backend to decide if we do or do ot want to include the check on email address for the count of number of times a coupon has been used

I have seen all these links but they don't provide any solution. What I want to check on email address for guest users,if email address already associated with any order and used the coupon code,then next time the coupon code won't be applied.

If you want to contribute to or report a missing feature you can do this here. If you want other people to help you find a solution to a specific problem and/or explain your problem and the steps you have taken to investigate - maybe you can ask the question on stackexchange? http://magento.stackexchange.com/.
